1912. Serial no. 639,740. I

To all to hem it may concern Be it known that we, HERMAN HAYssnN and ARTHUR H. HAYssEN, citizens of the United States. and residents of Sheboygan, in the county of Sheboygan and State of Wisconsin, have invented new and useful Improvements in DoughFeeding Machines; of which the following is a description; reference being had to the accompanying drawings, which are a. part of this specification.

This invention relates to improvements in dough feeding machines particularly adapted for feeding dough to weighing and dividing machines used in bakeries or other places where large quantities of loaves of bread are baked.

'In the modern bakeries machines are used for weighing and dividing the dough-into pieces of uniform weight and in orderto expedite the operation it is desirable to roll the batchof .doughto a certain convenient size and then feed the rolled dough to the weighing and dividing machine.

It is one of the objects of this invention to provide a dough feeding machine which is adapted to form dough into a roll' of a certain convenient size and to feed said roll in a.continuous stream to a: weighing and dividing machine. I

' A further object of the invention is to provide a. dough feeding machine which is simple in construction and operation andin which theroller mechanismis adapted to roll the batch of dough into form and to also advance the same. 1 i 7 WVith the above and other objects in view, the invention consists .of the improved dough feeding machine and its'parts and combinations as set forth in'the claims, and all equivalents thereof. v I

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views: Figure 1 is a vertical sectional view of-the improved dough feeding machine taken on line 1-1 of Fig. 3, a portion of the supporting frame being omitted; Fig. 2 is an end elevation thereof; Fig. 8 is a top View of the dough feeding machine with the upper portion of the machine removed'to show parts therebeneath; and Fig. llis a detail View of a" pending annular said opening ,and into which extends the.

standard 11 upon which is mounted the feeding mechanism. A bevel gear 12 pro vided with a tubular hub-portion 13 depend PatentedJan. d,

ing therefrom is journaled in a projection 14 extending atan angle forwardlyfrom the'istandard 11.. This bevel gear 12 is driven by means of'a bevel pinion 15 car-' riedby the main .drive shaft 16 whichis journaled onfthe standard 11 and is provided with a belt wheel 17 for belted connection witha source of power. The bevel gear 12 has extending inwardly therefrom bearing lugs 18 in which are-journaled conical' feed rollers 19. These feed rollers ex tend upwardly and outwardly at an angle and form a funnel shaped spout to receivethe batchof dough from the revoluble hop per2O mounted above thesaid feed rollers.

The upper and larger ends of these feed rollers are journale'd in bearings 21 carried by arms 22 extending upwardly from the bevel gear, 12.1..lhefeed rollers are also positioned at a: tan-gentwith relation to the axisof the bevel gear12with the lower ends of the feed rollers extending in advance of the upper ends of said rollers in the direc tion of rotation of the bevel gear 12; These rollersare formed with sli htly enlarged portions-23 sov that their adjacent'periphcries will just clear each other and form a spout substantially closed on the sides- A hopper plate 24: bolted'to, the,v standard. 11

and extending over the feed'rollers is pro vided with an opening 25and with a de flange 25" surroundlng lower end of the revoluble hopper 20. The outer periphery of the depending annular flange is provided with gear teeth 26 which arein mesh with gears 27 carried on the upper ends of the feed rollers to cause the rotation of said rollers while they are re volving with the bevel gear 12, thus provid ing a means for feeding the" dough downwardlywithout rubbing or undue handling or working. The revoluble hopper .20 is supported by and hasv a ball bearing connection 28 with the hopper plate 2% to permit thefree turning of the said hopper by Contact with the batch of dough which is'being turned by the feed rollers. The ball bearing connection is supported on arms 29 extending upwardly from the hopper plate 24:.

'An'e'ndle'ss apron 30 positioned beneath the ioo discharge opening of the spout and mounted on rollers 31 and 32 is adapted to receive the dough discharged in a flexible, cylindrical, continuous stream carrying it to the cutting and weighing mechanism (not shown) of a dough weighing and dividing machine. A guide roll 33 positioned above the endless feed apron serves to guide the dough in proper position on the apron and prevents the apron from drawing the dough at an angle against the side of the discharge end of the spout. A roller 3% adjustably mounted above the feed apron 30 near the outer end thereof is adapted to flatten the cylindrical stream of dough and regulate the thickness of the mass discharged therebeneath. The adjustable roller is journaled in the outer ends of the upper arms of the bell crank levers 35 mounted on the support 36 of the apron. The lower arms of these bell crank levers are provided with segmental elongated slots 37 through which extend bolts 38 to clamp the bell crank levers to the support when the roller has been adjusted to the height desired above the apron 30.

In operation a batch of dough is placed in the hopper and in the spout and the revoluble cone shaped rollers forming the Walls of the spout will converge and draw the dough downwardly, due to their angular and tangential position with relation to the axis of the spout. The dough will be discharged from the spout in a continuous stream, cylindrical in form, and will fall and lie prone upon the endless apron. The apron will carry the continuous stream of dough forwardly and in moving forward the dough will pass beneath the guide roller and the adjusted roller 2111': will be flattened thereby and be discharged from the apron in a most convenient form to be weighed and divided into pieces to form loaves.

From the foregoing description it will be seen that the dough feeding machine is simple in construction and operation and is well adapted to feed dough in a continuous stream without rubbing or undue handling. It is to be understood that this invention is not limited to any specific form or ar-- rangement of parts except 1n so far as such limitations are specified in the claims.
